I first adopted my K. Blossfeldiana about a year ago from a friend of mine. When I got it, the flowers had all wilted and were falling off. Since then, it only blossomed around 2 or 3 flowers (single flowers, not bunches). Moreover, the bigger leaves fell off and new leaves never grew to the same size. Still, it never stopped growing more stems and leaves and is much larger now than it was when I first got it.
What worries me about it is that some of the leaves are yellowing and that some of the leaves curl inward towards the stem. The yellowing leaves aren't crispy, but soft. I expect this is due to overwatering, so I'm not overly worried about it. I've reduced my waterings since then. At times, the leaves will bend downwards from their base at the stem. The leaves themselves will look fine, but they won't be perpendicular to the stem. Is that normal? If not, any comment on what the cause could be is greatly appreciated.
Finally, the tallest stem is somewhat flimsy and is leaning to the side. Is it normal for it not to hold its form?
There probably isn't much wrong but I am somewhat of a doting plant owner and want to make sure my plant is doing fine. There are pictures of the plant linked below. Thanks in advance!
